Methodology
Immunochemiluminometric Assay (ICMA)
Setup Schedule
Set up: Mon, Wed, Fri a.m.; Report available: 3 days
Limitations
Heterophil antibodies may produce falsely-elevated results.
Reference Range
| <0.10 ng/mL | After radical prostatectomy | ||
| ≤4.0 ng/mL | In healthy males without prostatectomy |
Clinical Significance
For post-prostatectomy patients.
The lower limit of accurate quantification for this assay is 0.02 ng/mL. PSA values less than 0.02 ng/mL cannot be accurately measured and will be reported as less than 0.02 ng/mL. Specimens with PSA levels below the lower limit of accurate quantification should be considered as negative. In patients with a negative result for post-prostatectomy PSA, serial monitoring of PSA levels at regular intervals, along with physical examinations and other tests, may help to detect recurrent prostate cancer.
